VALVE-OPERATING MECHANISM roa vAroaBURNEns.

Be it known that L osnonnnEqQumro v, a citizen of'the United States of America,

residing at Chicago, in the county of Cook and State'of Illinois, have invented certain new {and useful Improvements in Valve- Operatlng Mechanism for Vapor-Burners, of WhlCh the followlng s a specification,

reference-being had therein to the accom panying drawingl. 2

Vapor burners, using hydrocarbon fuel and designed for pa1nt burners, heaters,

torches and such apparatusrequire intense heat, Valvular mechanism is employed for controlling the supply of fuel to the burners and after some experience with this "particular vapor burner it has been found dei ective in one particular,'namely, that of permitting air to escape from the reservoir when the reservoir s n one positlon.

. The primary obgectflof this invention 18 to provide a novel valvular construction which will at alltimes prevent air from escaping from the reservoir and thus imalntain the air within. the reservoir for fuel feeding purposes, irrespective of the positionin which the reservoir is placed.

A further object of my invention is to provide a valve actuating mechanism that may be easily installed in a fuel reservoir and as readily removed therefrom, the valve operating mechanism being automatic to the extent of depending on gravity for opening and closing the valve, andthe arrangement ofthe mechanism is such that its operation isp'ositive .witha minimum amount of wear on the movable parts ofthe mechanism- The above and other obj cots are attained by a mechanical construction that will be my invention;

" accordance with this invention.

hereinafter more fully described and then claimed, 'and'reference-will. now be had to the drawings, wherein I 7 t I Figure-1 is a longitudinal sectional view of a reservoirprovided with a valve and operating mechanism ina'ccordance with Fig. 2 is a cross sectional view of the same;

The extension 10' has a face thereof cut away or recessed, as at 18 andfprovided with" a valve seat member 1 1 at the inner Adjacent the opposite end end'of the connection 8, which is adapted to communicate with tubular valvularmember 12 when the end of said member engages the valve seat member 14, as shown inv 1. The end of the tubularvalvular member 12 may be conical or otherwise shaped so thatit will positively engage the valve seat member 14; and close the communication between the connection 8 and that'end of the reservolr 1 containing the extension 10. g I

Mounted on the tubular valvular member 12 is ayoke 15"having side arms 16 engaging the side walls of the extension 10,

the yoke 15 receives actuated member which is supported relative to theextension- 10 by side pins 23 .of the arm 21 extending into the sidewalls of the extension 10, and the side walls of said extension are beveled, as at 2 1, so thatthe arms 21 may be placed downwardly over the extension 10 and [forced apart whereby the pins '23 may engage in the pockets, or recesses provided thereforinthe side walls of the extension.

nected to said valve adapted to automatically actuate said valve to provide an outlet for fuelat the opposite end of said reservoir.

5. A reservoir as characterized in claim 4, wherein said means includes a weight, resilient arms connecting said weight to said valve, and means adapted to spring said arms by withdrawal of said means from said reservoir to release said arms relative to said valve.

6. A reservoir for vapor burners adapted to contain a fuel under air pressure and provided with a filling connection, a burner con nection at one end of said reservoir having an extension in said reservoir, a tubular valvular member slidable in the extension of said burner connection and providing a constant outlet for fuel at one end of said reservoir and adapted to be shifted to provide an outlet for fuel through said burner connection at the opposite endof said reservoir, and a gravity actuated'device pivotally connected to the extension of said burner connection and adapted to shift said tubular valvular member.

7. A reservoir as characterized in claim 6, wherein said device is insertible through the filling connection of said reservoir and detachably connected to the extension of said burner connection. 8. The combination of a portable reservoir adapted to contain fuel under air pressure and provided with a filling connection, a burner connection atone end of said reservoir, constantly communicating with the 0pposite end of said reservoir and adapted to communicate with the burner connection end of said reservoir, and gravity means insertible through the filling connection of said wherein said gravity means includes a weight adjacent to filling connection of said reservoir and adapted to swing from one side of the transverse plane of said filling connection to the other side thereof.
